As the market demand for high-quality, low-weight corrugated board continues to grow, the efficiency and quality of the traditional production line is no longer sufficient to meet customer expectations. As a result, we have completely revamped our five-layer corrugated board production line, focusing on upgrading the Gluing Machine and Preheater. This article describes the details of the revamp and the significant benefits it has brought.


Contents of the retrofit
1. Gluing Machine


Precise control of gluing volume: The upgraded gluing machine adopts an advanced gluing control system, which can precisely control the gluing volume and ensure even distribution of glue on each cardboard.
Increased automation: The new gluing machine integrates an intelligent control system that reduces manual intervention and improves productivity and consistency.
2. Preheater (Preheater)


Optimized temperature control: The retrofitted preheater employs high-efficiency heating elements and a precision temperature control system to quickly and evenly preheat the cardboard to ensure that it remains in optimal condition in the following processes.
Energy-saving design: The new preheater adopts an energy-saving design, which reduces energy consumption, lowers production costs and is more friendly to the environment at the same time.
Advantages of Retrofitting
1. Glue saving


By upgrading the gluing machine, we are able to control the amount of glue used more accurately, avoiding overuse and saving significant glue costs. The optimized gluing process not only reduces waste, but also ensures strong and stable cardboard bonding.
2. Increase average speed


The upgrading of the preheater enables faster and more uniform preheating of the board, reducing the risk of board breakage and deformation during the production process. The more efficient preheating and gluing system increases the overall average line speed and significantly improves production efficiency.
3. Improvement of low weight board quality


Low-weight board is more susceptible to damage during the production process, and the retrofit provides more precise control and a more stable production environment, which significantly improves the quality of low-gravity board. Uniform heating by the preheater and precise gluing by the gluing machine make the low-gauge board outstanding in all performance indicators.
Conclusion
The renovation of the five-layer corrugated cardboard production line has not only significantly improved production efficiency, but also taken a new step forward in product quality. We believe that through continuous innovation and technological upgrading, we will be able to better meet the diversified needs of our customers and provide them with higher quality corrugated board products.
